Solid-state image capture device and image capture apparatus
View Patent ↗A solid-state image capture device includes photoelectric conversion elements that perform photoelectric conversion on incident light to obtain signal charges, color filter portions provided at light incident sides of the corresponding photoelectric conversion elements, and an organic photoelectric conversion layer provided at light incident sides of the color filter portions. The organic photoelectric conversion layer contains a pigment that is absorptive of near infrared light.
1. A solid-state image capture device, comprising:
photoelectric conversion elements configured to photoelectrically convert incident light into signal charges;
color filter portions provided at each light incident side of the photoelectric conversion elements;
a first photoelectric conversion layer,
wherein, the first photoelectric conversion layer is an organic photoelectric conversion layer provided at each light incident side of the color filter portions, and
wherein, the organic photoelectric conversion layer contains a pigment that absorbs near infrared light; and
a second photoelectric conversion layer,
wherein, the second photoelectric conversion layer is between the color filter portions and the first photoelectric conversion layer to absorb infrared light having a longer wavelength than the near infrared light absorbed by the first photoelectric layer.
2. The solid-state image capture device according to claim 1 , wherein the color filter portions have a color filter portion that is absorptive of red light, a color filter portion that is absorptive of blue light, and a color filter portion that is absorptive of green light.
3. The solid-state image capture device according to claim 1 , wherein, the first photoelectric conversion layer is operable to output a near infrared-light signal; and
wherein the second photoelectric conversion layer is operable to output an infrared-light signal.
4. The solid state image capture device according to claim 1 , wherein the pigment includes at least one of quinoid-based metal complex pigment, cyanine-based pigment, immonium-based pigment, diimmonium-based pigment, triarylmethane-based pigment, naphthoquinone-based pigment, anthraquinone-based pigment, squarylium-based pigment, phthalocyanine-based pigment, naphthalocyanine-based pigment, anthraquinone-based pigment, and nickel-dithiol-complex-based pigment.
